@brecht, seems to be this old bug again: keyframed properties reset all the time.

Here's a simpler version of the file that reproduces the issues.
cant_transform_bbone_armature.blend

The problem is that there is a keyframe on the armature edit mode bbone ease-in property, instead of the pose mode bbone ease-in property. Changes to the armature datablock cause the object pose animation to be re-evaluated.

It seems that in 2.79 insert keyframes on the button causes this kind of wrong keyframe, while in 2.80 it's actually working correctly.

@angavrilov, maybe one of your changes fixed this? We could try to do some versioning to fix such paths in existing files, not sure it's worth the complexity.

To be clear, e.g. pose.bones["Bone.001.L"].bone.bbone_easein should be pose.bones["Bone.001.L"].bbone_easein.

To be clear, e.g. `pose.bones["Bone.001.L"].bone.bbone_easein` should be `pose.bones["Bone.001.L"].bbone_easein`.

Until recently PoseBone.bone didn't change id_data to point at the Armature ID, so keyframing or adding drivers via "bones- [ ].bone" would insert keys into AnimData of the armature Object. For backward compatibility reasons it probably should work though - for drivers at least I made sure that depsgraph etc is correct for such misplaced cases.

Brecht Van Lommel changed title from ~~Armature action corrupted, Can't transform any bone~~ to Armature with bbone keyframes from 2.79, can't transform bones

Seems to work fine here as well.

I close this for now. @pepe-school-land, feel free to reopen this report if you are able to reproduce the issue in the latest build.
